Knob on oven is not working properly

Hello -

Please double check for the model number. It will probably be on a small metal plaque on an edge of the oven door, along the outer edge of the oven opening, or in the oven interior. It could also be on the top of the oven and covered by cabinetry.

Undo the screws that hold the oven in and slide it out 6 inches. You may then find the metal plaque on the top of the oven. You may need the help of another person when you try to pull the oven out, so that the oven does not tilt forward and fall to the floor.

You MAY be able to identify your model of Diplomat oven from one of the images of Diplomat oven control panels here:

Once you know which model of Diplomat oven you have, you may be able to find and purchase decals with the proper knob markings for your oven so that you can affix the decals around your oven knobs. Or, you could use heat resistant paint and a small, pointed paint brush to paint the markings on your oven. With either option, I suggest you seal the markings with a heat resistant clear sealant so that cleaning / scrubbing will not erase the markings.

Best wishes.

First try a layer of silver paper around spindle.

If not satisfactory then try a "No nails" type of clue.

get in a gas fitter as there is a burner problem
probably best if you junk it and get a new unit
much safer with gas units

Hi.

After power cuts most ovens need resetting, for this reason 00:00 is flashing. The operation is described in the specific model's user manual. Most ovens reset either pressing or holding down for few seconds a Clear or On button, or holding down the main control knob.

Hello everytime the power goes off & then comes back on my oven won't work until I turn the knob for the timer around as far as it will go then back again. My oven is rather an old type but maybe if you reset the timer or turn it that may help. Or check the meter box as well. dee

Is the oven gas, if so you may find that it is fitted with a thermocouple (safety cut out) and to get the oven working you need to hold the knob in for around ten seconds after the oven is lit to activate the safety device. If it has a clock timer check it is not on auto and the time is set 'cos that will also stop the oven working.
All the best, pls leave feedback or repost with further information.

You should pull the knob off and check that there is a metal liner in the knob itself. These sometimes fall out and the plastic knob does not turn the control properly. Get a new knob at your local appliance store.

Pull the knob off of the oven control and see if their is an ajustment. If the ajustment doesn't work then change the thermostat bulb. It goes for the oven to the back of the oven control know

Hi.
You need thermostat knob and main oven control knob.

Simply set the Clock and Delay Start to the current time, then set the Stop Time ahead 3 hours. For example, if it is currently 8:00 then set the Stop Time to 11:00. The lights on the console will come on and the cleaning cycle will begin. At some point during the cycle when the oven gets hot enough, the lock mechanism is "fixed" and will not release until the cycle is complete.
